1.Excel VBA点击单元格时执行事件！

Private Sub Worksheet_SelectionChange(ByVal Target As Range) 
If Target.Column = 1 And Target.Count = 1 Then 
MsgBox "你选中了:" & Target.Text 
End If 
End Sub

2.在excel中，要实现光标离开单元格触发一个事件

Dim address As String
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
MsgBox "光标离开了 " & address & ",移动到了 " & Target.address
address = Target.address
End Sub

3.excel vb中读取单元格的位置信息

Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)
MsgBox "显示列数" & Target.Column
MsgBox "显示行数" & Target.Row
MsgBox "显示当前工作薄的名字" & ActiveWorkbook.Name
MsgBox "显示当前工作表的名字" & Sh.Name
End Sub

例子：

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim column As String
Dim line As String
Dim value As String
column = Target.column
line = Target.Row
value = Target.value

MsgBox "位置:" & line & "," & column & ",value:" & value

MsgBox value = "AA"
MsgBox value = ""
End Sub
